SEALING nnvrcn roe JARS.

Specification of Letters Patent.

Patented Feb. 21, 1922 T 0 all whom it may concern:

Be it known that I, BURT E. TAYLOR, a citizen of the United States,residing at Mount Vernon, IVestchester County, State of New York, haveinvented certain new and-useful Improvements in Sealing Devices forJars, of which the following is a full, clear, and exact description.

This invention relates to improvements in sealing means for jal'smoreespecially preserve jars. The object of my invention is to provide ameans whereby the vacuum can bebroken, thereby rendering the operationof removing the tops of a preserve jar an easy matter. It is a wellknown fact that the tops of jars have to be pried off, or slightlyraised along a portion of the edge thereof, in order to break thevacuum. Preserve jars are usually sealed while heated, that is to say,thematter to be preserved is placed .in the jars, and the jarscompletely filled .while the jars are hot and also while the matter to'be preserved is hot; in fact thejars are usually placed in hot water andfilled, the jars being sealed while heated; hence all air is excluded.After the jars have cooled off and the tops are to be removed, say forinstance some months later, the tops of the jars have to be pried off,or as has been stated, slightly raised along a portion of their edges tobreak the vacuum. I am aware that means have been provided to facilitatethe removal of these tops, such for instance as providing the tops withopenings therethrough, said openings being covered by a rubber pad heldin place by yieldable resilient strips. One of the objections to thisform of tie vice is that the openings become plugged with the candiedsyrup within the jars or else the rubber pads become vulcanized and leakor else plug the openings. One of the objects of my invention is toprevent the candied syrup from plugging the opening or to prevent theplugging of the opening from any cause.

In the accompanying drawing, I have illustrated means which I prefer toemploy to carry out my invention.

Referring to the drawing- Fig. 1 illustrates an embodiment of myinvention;

Fig. 2 is an enlarged cross sectional view, the section being taken on aline 22 in Fig. l;

Fig. 3 illustrates a modified form of my improvement; and

Fig. 4: is an enlarged detail view of the vacuum relief valve employedin connection with the modified form of my invention.

In the accompanying drawing, a portion of a preserve jar is indicated by5 having a neck 6, carrying threads 7 to receive the threaded bodyportion 8 of a securing ring 9 to maintain the top 10 of the jar inposition. Between the top 10 and edge 11 of the jar, agasket 12 islocated, said gasket being usually made out of rubber. The functionofthe ring9 is to force the top 10 against the gasketl2, which in turnis forced against the edge 11 of the neck '6 to maintain the jar airtight, aiter'matter to be preserved is placed within the jar 5. As hasbeen stated, the top 10 will be placed in position, also gasket 12, andthe securing ring 9 applied while the matter within the jar is in heatedcondition, and as the jar will be completely filled, there will be noair within the ,jar' after it has cooled off and the vapors within samehave con densed. In other words, the contents of the jar will be undervacuum after it has cooled off; hence the top 10 will have considerablepressure thereupon, and in order to remove same considerable force isrequired unless the vacuum is broken. To break the vacuum, in order torender the top 10 easily removable, I provide special means in the formof an opening 13 through the top 10, a valve 1 1 therefor and ayieldable resilient strip or spring 1.5, the ends 16 of which, in thisinstance, are caught under the flange 17 of the securing ring 9. Thevalve 14 (in this instance) consists of a stem 18, which passes throughthe opening 13, carried by the strip 15, and a yieldable pad member 19,preferably of rubber, which is considerably larger than the diameter ofthe opening 13. The object of the stem 18 is to entirely fill theopening 13 to prevent syrup from within the jar to enter same and becomecandied, thereby plugging the said opening, and also to assist the pad19 in performing the function of preventing air from prematurelyentering the jar through the opening 13. The function of the spring 15is to force the pad tightly against the top of the jar to seal theopening 13, but the stem 18 assists the pad to a large extent as itcompletely fills the opening 13; hence the chances of leakage aregreatly lessened more so than ii the stem was not employed. The spring15 and its valve lawill be placed in position before the ring 9 isapplied, and the ends 16 of the spring will be positioned as indicatedby dotted lines (Fig. 1.). hen the ring is applied, the ends of thespring Will be forced down thereby forcing the pad 19 firmly against thetop. When the top is to be removed, it is but necessary to remove ring 9and pull the spring 15 and valve 14: off the top 10, after which airwill flow in to the jar through opening 13. The top 10 may now be easilyremoved. 2

Fig. 3 illustrates a jar 20 having a top 21 which is held by a clampingdevice instead of a retaining ring, said clamping device being the usualhasp 21 connected at its end to a lever device 22 which in turn ispivotally connected to a supporting band 23 carried by the jar 20. Thisform of clamp is well knownand'needs no further description. In thisform of my invention, I employ a valve mechanism 24; consisting of acarrier 25 provided witha pin 26 to enter and fill the opening 27 in thetop 21. The carrier also supports a pad 26, preferably of rubber. Thevalve 24 performs the same function and acts in the same manner as valve14 in the form illustrated in Fig. 1, excepting pressure is supplied bya clamp instead of a spring.

The carrier 25 projects beyond its pad 26 in order that the valve can bepried'ofi without injuring the pad.

Having described my invention, what I claim is 1. In combination with acover or top for jars, having an opening therethrough, a valveconsisting of a yieldable pad to cover said opening, and a stem to entersaid opening together with means to force the pad firmly against thesaid cover or top, said valve and cover being arranged to be removedfrom said cover simultaneously.

2. The combination of a jar, a top or cover for same having an opening,and a ring member to secure the cover to the jar, a resilient strip, astem carriedthereby to enter and approximately fill the opening in saidcover, a yieldable pad member carried by the strip and surrounding thestrip and stem at the point of securement'of the stem to the strip, theends of the resilient strip being arranged for insertion between thecover of the jar and securing ringtherefor, whereby said pad will beforced against the cover when saidring is screwed down.

3. In combination with a jar having a top provided with an opening, andmeans to secure the top to the jar, a valve mech anism to close saidopening, consisting of a carrier provided with a pin to enter theopening "in the top, and a yieldable pad carried by the carrier andsurrounding said pin at thepoint of securement of the pin to thecarrier, said carrier extending beyond the ends of the pad to providemeans to enable the valve to be pried off the top of the jar withoutinjuring'the pad.
